vTo @ZZ whom t may concern:

Be it hereby known that I, JOHN W. SHAW- VER, a citizen of the UnitedStates, residing in Portland, in the county of Jay, and in the State ofIndiana, have invented new and useful Improvements in Well-DrillingMachines, of which the following is a true specification, by which, whentaken in connection with the accompanying drawings, forming a partthereof, a full and complete understanding ma be had of my invention bythose skilled in tl e art to which this invention relates. The object ofthis invention, broadly stated, is the production of improvedwelldrilling machines in which a maximum of mechanical efl'iciency'maybe developed with a minimum of power applied, while at the same timeproviding a machine composed of a minimum of mechanical parts consistentwith the work it is adapted to perform.

y Another generic object is to provide a welldrilling machine which willbe neat, artistic and attractive in appearance, compact and symmetricalin its proportions, strong and durable in construction, positive inaction, and capable of a wide scope of usefulness and efliciency.

A more specific object of my invention is to provide a well-drillingmachine in which the various parts and mechanisms are so positioned andarranged that the weight will be evenly divided among the variousbearings and supports, while at the same time preserving the properalinement and the most advantageous working points for the variousmechanisms.

Other specific objects are: to provide awelldrilling machine or rigmounted on two or more sets of trucks of four wheels each, whereby therig may be more easily transported from job to job to provide means forfolding the Walking-beam mechanism to provide a new construction inwalking-beams, and to generally improve the specic and generalconstruction of well-drilling machines and the like.

Other minor objects and advantages of this invention will be mademanifest 1n the course of the ensuing specification.

My invention consists in a well-drilling machine containing the severaldistinguishing features stated and the relative disposition of theseveral parts, substantially as particularly described elsewhere in thisspecification and in the legitimate combinations herein set forth withreference to each other and to the machine as an entirety.

Referring now to the drawings forming a part of this specification for avisualization- Fig. 4 is a top plan of the parts shown in Fig.

3. Fig. 5 is a side view, same as shown in Fig. 1, except that thewalking-beam mechanism is shown folded ready for transportation. Fig. 6is a side elevation of the upper portion of the derrick. Fig. 7 is afront view of the upper portion of the derrick. Fig. 8 is an isometricalview of the center portion of the walking-beam, and Fig. 9 is anisometrical view of one of the end members of the walking-beam Similarreference characters denote and refer to like parts throughout theseveral views of the drawin 's.

With all of the a ove-designated views in mind and for the purpose ofmaking my invention more clear to those unfamiliar with the art to whichit appertains I will now take up the detail description thereof and willrefer to the essential parts as briefly and compactly as I may.

Reference is now had to the drawings in detail.

Front section-The letters A and A denote the two side or main sills ofthe front section of the machine, their greater central portions beingconnected and spaced apart by the relatively long block a, while theirrear ends are connected and spaced apart by the gib-block a', and Whichlatter rises somewhat above the main sills, as shown in Figs. 1 and 5.

The letters B and B denote the auxiliary front sills, the formerextending out from between the front end of the main sill and the latterextending out from the side of the main sill A, as is shown in Fig. 2.Underneath and toward the rear of the main sills is permanently securedthe axle C, which projects out at either side to receive thegroundwheels D and D, and underneath the forward ends of the auxiliarysills B and B is pivotally mounted the axle C', which projects out ateither side in alinement with the axle C to receive the ground-wheels dand d.

TOO

IIO

The letter E denotes a tongue attached to l the front axle C Secured tothe outer face of the side of the sill A near its forward end and risingsome distance thereabove is the standard 1, and corresponding therewithand located out some distance to the right therefrom is the standard 2,the latter being supported as follows: Extending across underneath theforward portions of the sills A A and projecting some distance to theright are the parallel supports 3 and 3, across the outer end of whichis secured the plate 4, from which latter rises the said standard 2,being provided with the braces 5 and 5, and the upper ends of the saidstandards 1 and 2 are connected by the metal bridge 6. A horizontalshaft 7 extends through and between the central portions of thestandards 1 and 2, on which shaft is mounted the combination pull-wheel8 and the drum 9, which are permanently connected together, as shown. Onthe outer end of the shaft 7 is secured the crank 10. A belt 11 may beplaced over the pulley 8 and then extended to the powerfor instance, anengine.

Kin -post.-Resting on and rising vertically from t e sills A A is thetwo-p art king-post 12, whichrests on said sills at points directlyabove the axle C. The king-post 12 is hinged to the main sills by hinges13, whereby the kingpost may be folded forward, as in Fig. 5. Theking-post is braced when erectv in working position by the removabledouble brace 14 in front, which extends up from the main sills at anangle to near the top of the kingpost, and also by the double brace 15in the rear, which extends up from the main sills at an angle to nearthe top of the king-post, its lower end being hinged to the sills byhinges 16. /Vhen erect, the king-post is further secured to thel sillsby a pair of clips 17 17, bolted to the faces of the sills A A and thenextending up the sides of the king-post, where they are removablyconnecte by a bolt 18, which passes throu h an eye in the upper ends ofthe clips anc passes entirely through the king-post, as shown. Mountedacross on the front edge of the king-post is a shaft 19, carried insuitable boxings, being provided at one end with the crank 20, wherebyit may be revolved by hand. In the forks of the upper end of theking-post is located a pair of boxings in which the axle of thewalking-beam may oscillate.

WaZcc'ng-beam-dMy walking-beam is of a peculiar novel construction andconsists of three rods or bars of equal lengths spaced apart and securedin their centers by the coupling 21, having three separated and parallelapertures therethrough to receive therethrough the said rods or bars,which latter are denoted by the numerals 22, 23, and 24. The ends of thesaid rods are brought near together at their ends, where they aresecured in the end members 25 and 26, front and rear, respectively.Secured acrossin the center of the coupling 21 is the shaft 27, which isadapted to operate in the boxings referred to in the upper end of theking-post 12, by which it will be seen that the walkingbeam is mountedbetween the forks of the king-post, as shown in Figs. 1, 2, and 5. Theouter end portions of the end members 25 and 26 are concentrated andsomewhat flattened, forming an eye portion for attachment thereto ofother working parts.

The numeral 28 denotes a connecting-rod pivotally mounted at one end insaid eye portion of the end member 25 and then extending down, where itis removably pivoted to the wrist-pin of the crank 10, being removablyattached at the latter point by the employment of the key 29. In the eyeof the end member 26 may be attached the desired tools for operating inthe well being formed directly therebelow-that is, in the center and inthe rear of the main sills above mentioned.

Sandreel mechantsm--Rising from the auxiliary sills B and B are the twohangers 30 and 30', respectively, having boxings thereon at theircentral apex, in which is mounted the shaft 31, which shaft extends tothe right beyond the sill B on which projection of said shaft is securedthe frictionwheel 32, which is adapted to have its periphery contactwith and be released from the periphery of the pulley-wheel 8, theoperation of which is accomplished as follows: The numeral 33 denotes aplatform extending across and beyond the surface of the sills A and A ata point in the rear of the king-post. Secured on top ofthe platform 33,toward each end thereof, are hangers 34 34', in which is mounted the rod35, which has a lever 35, turned at theleft end, and a crank 35a,'turnedat the other end, all as shown in Fig. 2. The numeral 36 denotes a rodconnected at one end to the crank 35a and at the other end being securedaround the shaft 31, as shown, whereby as the lever 35 is operated theface of the wheel 32 is brought into contact with or is moved from theface of the wheel 8. Mounted on the shaft 31 between thelauxiliary sillsB and B Vis a spool 37, adapted to have wound thereon a cable or thelike to extend up over the pulley 38, located in the upper portion ofthe derrick for operating the sand-pump or the like in the well beingformed. Rear sembra-The characters 'F and F denote the two side sills ofthe rear section of my machine, which sills are spaced apart and areconnected by the center sill G, and at their ends next the front sectionthey are connected by the top plate or platform H, which plate orplatform vis notched in its cuter central portion to receive the ends ofthe main sills of the front section of the machine, as shown in Fig. 4.

IOO

The characters lV and I denote the two connecting-plates pivotallybolted to the under side of the top plate H outside the sills F F andwith their free ends adapted to be secured detachably to the under sideof the platform 33 by bolts or otherwise to connect the front and rearsections of the machine. The rear ends of the rear frame are connectedby the cross-sill J, and just in the rear of the center sill G the mainsills are connected by the tie-bolt K. f

The figures 39 and 40 denote a pair of hounds secured on the tie-bolt K,converging toward each other outwardly, secured near their centers tothe sill J, and extending` therebeyond centrally of the rear portion ofthe machine, their ends being spaced apart and secured by the cross-tie41, secured on their under edges.

The letter L denotes the front axle of the rear section of the machine,which is permanently secured to the under side of the sills F F, itsends projecting beyond said sills and being provided with theground-wheels M and M. Pivotally mounted in the center to the under sideof the center of the tie 41 is the axle L, on the outer portions ofwhich is mounted the ground-wheels N and Nl Rising from the sides of thesills F and F is a frame composed of the perpendicular posts i `42 and43, which posts are connected at the top by the cross-tie 44, said framebeing braced by the two angularly-disposed braces 45 and 46, whichbraces extend upward and rearward from the top of the plate H to nearthe top of the posts 42 and 43.

Mounted horizontally between the posts 42 and 43 is the shaft 47, havingsecured thereto near the post 43 the channel-wheel 48, its face beingprovided with two parallel channels to receive a rope or cable belt, andalso secured on the shaft 47 near the post 42 is the friction-wheel 49.Thus it will be seen ythat a rope or cable may be wound on the lresponding to the curvature of and a slight Vdistance from the wheel 49is the guard 50,

itlsllower end being attached to the end of the si F.

Pivoted to the top of the sill F, below the forward segmental portion ofthe wheel 49, is the permanent end of the spring frictionband 51, whichpasses over substantially three-fourths of the periphery of thefrictionwheel 49 and endingl slightly in the rear of the permanent endthereof. The free end of the said friction-band is attached to the crankof the lever 52, which is mounted on top of the sill F in rear of saidpermanent end. It will now be apparent that by moving the top of thelever 52 forward said friction-band may be caused to grasp and hold thewheel 49, and therefore the entire reel, from revolving or in order toallow it to revolve at the desired rate of speed.

The danach-The derrick is formed primarily of three upwardly-convergingposts, (denoted by the figures 53, 54, and 55,) each being formed inseparable sections, as indicated, whereby they inay be taken apart fortransportation. rlhe iirst two denoted posts rise from the sides of themachine, while the latter rises from the rear of the machine. The posts53 and 54 are connected at their lower ends by the cross-sill 56. l/Vhenin position, the cross-sill 56 should extend across underneath themachine immediately in the rear ofthe rear wheels of the front sectionof the machine, as is indicated in the drawings, and should be supportedfrom the ground by the mud-sills 57 and 58, and in practice I have foundit advisable to have the mud-sills formed in sections and extend fromend to end of and underneath the machine, which may be provided withsuitable cross-ties (not shown) bolted thereacross and then to have thecross-sill 56 bolted or otherwise secured to the mud-sills after thederrick is positioned.

The numerals 59 and 6() denote scotchblocks bolted to the mud-sills toprevent the posts 53 and 54 from slipping when the derrick is beingraised or lowered.' The posts 53 and 54 may be reinforced by securingthereto a cleat P, as shown in Figs., 2 and 4. The said posts 53 and 54may be further secured by means of cross ties and braces as, forinstance, the tie 61. (Shown in Fig. 7.) The upper ends of the posts 53and 54 are spaced apart, and yet rigidly secured by the employment ofthe crown or boxing 62, Figs. 6 and 7, which is bolted together and thensecured to the sides of the posts 53 and 54, and on the forward side apair of braces 63 and 63 extend down therefrom to the respective posts53 and 54, as shown. Extending through the center of two opposite sidesof the crown and also through the posts 53 and 54 at that point is anaxle-bolt 64, on which is mounted the pulley-wheel 38, above referredto. Securely mounted from and extending below the lower edge of the tie6l is the pulley 65, over which a rope or cable may be passed foroperations in the well being formed. The third post 55 has on its upperend a harp or two-pronged member 66, the ends of which prongs arepivoted on the axle-bolt 64 out.- side the sides of the crown 62, asshown in Figs. 6 and 7. The lower end of the post 55 is mounted on apair of ground-wheels 67 and 67, which are on the axle 68, which latteris secured centrally to the lower end of the pole 55, as shown in Figs.3 and 4. When in operative position, the lower portion of the pole 55just above the axle 68 is adapted to fit in between the points of thehounds 39 and 40, as shown in Figs. 3 and 4, where it may be heldsecurely by means of the retainer 69, the ends of which retainer areremovably secured IOOI IIO

ISO

by bolts to the cross-sill J, and the outer central portion of theretainer should be secured by the bolt to the lower portion of the post55, as shown. The numeral 81 denotes a pulley secured to the rearcentral portion of the sill J, over which pulley a rope or cable may bepassed for raising and lowering the derrick, which operation will bedescribed later.

Gaya-The numerals 71 and 71 denote eyes in which guy-lines (not shown)may be secured.

Operation-The work to be performed by this machine is immaterial to thisspecification, in that it is well known in the art. Suffice it to saythat the various operations of producing a well are to be performedherewith in substantially the same manner as are at present accomplishedby machines or rigs of this general character. For instance7 an engine(not shown) may be employed, over the drive-pulley of which the belt 11is operative, whereby the wheel 8 is to be revolved for operating thewalking-beam and for operating the sand-reel, and when both of the aboveare disconnected it may be used for raising'v and lowering the derrick,which last operation will'presently be described in detail. The numeral72 denotes a belt operative over the drum 9 and then over thechannel-wheel 48, whereby the shaft 47 is revolved. A rope or the like(not shown) is to be wound on the reel formed by the shaft 47 andthinner faces of the wheels 48 and 49, its free end being extended upthrough one of the pulleys in the upper part of the derrick and thenextending down into the well for accomplishing various operations.

Assembling cmd disassembling-In Figs. 1, 2, 3, 4, 6, and 7 are shownvarious parts of my machine, each part appearing in its operativeposition. Therefore for convenience I will first describe the operationof disassembling the parts and arranging them for transportation-thatis, for transferring the machine to a new job, there to be againerected. The iirst thing in disassembling the machine would be todisconnect the connecting-rod 28 from the crank 10, A rope or the like(not shown) is then secured to the shaft 19 and is then secured to somestationary object to the rear-as, for instance, one of the posts of thederrick-said rope passing through between the members of the king-post12. The front braces 14 are then removed, I then remove the bolt 18, andthen the king-post is allowed to turn forward on its hinges 13,controlled by the crank 20, The connecting-rod should be turned under torest on the sill B, allowing the center portion of the walking-beam torest on the upper end of the prop 73, the lower end of said prop beingrested on or in a cavity formed in the sills therebelow. As theking-post turns forward the rear braces 15 follow thereagainst andlinally lie thereon, and when thus arranged the parts of the frontsection will appear as shown in Fig. 5. Then by detaching theconnecting-plates I I from the platform 33 the front section of mymachine will be ready to be hitched to for removal. The next operationwill be the disassembling of the derrick. To accomplish this, the ropepreviously referred to as being wound on the reel 47 is removed from thepulley in the derrick, and after being wound on the reel the free endthereof is placed through the pulley 81, and its free end is thensecured near the base of the pole 55. The retainer 69 is then removed,and then by allowing the foot of the pole 55 to travel to the rear,carried on the wheels 67 67" and controlled by the lever 52, the derrickis lowered until it lies flat upon the ground, which, it is apparent,can be accomplished without injury to any of the parts. After beinglowered the derrick can be taken apart and loaded for transportation.The derrick being removed and the front section of the machinedisconnected, I now have only to secure a tongue between the rear partsof the hounds 89 and 40, and then the rear section of the machine willbe ready to be hitched to and hauled rearward. In assembling and settingup my machine it is apparent that the reverse of the above will benecessary except that in raising the derrick the belt 72 is placed overthe wheel 48 and over the drum 9 and the belt 11 is placed over thepulley 8 and over the drive-pulley of the engine, whereby the derrickmay be raised with the power from the engine. y

From the above description, whentaken in connection with theaccompanying drawings, it will be apparent that I have produced animproved well-drilling machine embodying the objects elsewhere referredto in this speciiication, and while I have illustrated and described thebest means now known to me for carrying out the principles ofmyinvention I desire that it be fully understood that I do not restrictmyself to the exact details of construction shown and described, buthold that any changes or variations therein as would suggest themselvesto the ordinary mechanic would clearly fall within the limits and scopeof my invention.

Having now fully shown and described my invention and the preferredmanner for its construction, what I claim, and desire to secure byLetters'Patent of theV United States, is-

In a well-drilling machine having in combination, two mainframe-Sections, groundwheels on which the said main frame-sections aremounted, an axle for each pair of groundwheels, the forward sectionhaving a walking-beam mounted thereon, the frame of said front sectionbeing formed of a pair of main sills spaced apart and extendin to therear beyond the rear wheels of said ont section IOO IIO
